Mechanical Notes:

Notes:

1. The specified maximum capacitive load is for each output.

2. Load regulation is measured for a load change of 20% to 100%.

3. When measuring output ripple, it is recommended that an external 0.47 µF ceramic

from each output to common for dual output units. For noise sensitive applications,

the use of 3.3 µF capacitors will reduce the output ripple.

4. Any units that are not packaged in a vacuum sealed container should be stored in a

controlled environment. Contact the factory for more information.

5. The recommended reflow settings are a peak temperature of 245 °C for a maxi-

For more information, please contact the factory.

6. Operation at no-load will not damage these units. However, they may not meet

all specifications.

7. Dual output units may be connected to provide a 24 VDC or 30 VDC output. To do

float the output common.

8. The converter should be connected to a low ac-impedance source. An input source

with a highly inductive impedance may affect the stability of the converter. In appli-

cations where the converter output loading is high and input power is supplied over

long lines, it may be necessary to use a capacitor on the input to insure start-up.

In this case, it is recommended that a low ESR (ESR <1.0

 at 100 kHz) capacitor

be mounted close to the converter. For 5V input units a 2.2 µF is recommended,

for 12V input units, a 1.0 µF; and for 24V units a 0.47 µF.

9. It is recommended that a fuse be used on the input of a power supply for protection.
